#1

1 or 2 lights?



Well, both is nice, but let’s examine the downside of both bulbs.



If one light keeps burning out, and not the other, then there is another problem, a short, or a cracked casing.



Also, the extremely hot, bright halogen bulbs have a warning, don’t get grease on them. Even the oils in your fingers can make them fail. Buy a pack of vinyl gloves to do the replacements with.



Remember bulbs are rated in hours, but that varies by the number of times they go on / go off (thermal cycles). If you drive longer trips, they tend to last more hours, if you tend to make alot of short trips, they will burn out quicker.


#2

I’m cheap. When one goes out, I but two bulbs, replace the burned out one and I will have #2 ready.

The last time I had a headlamp go out, I was driving back from NY to Ohio and as it got dark I found I no longer had head lights. I was happy to have fog lights.
